<p><P>PROBLEM TO BE SOLVED: To provide the controller of a conveyance carrier for continuing traveling as much as possible without immediately stopping traveling even when the rotation of a touch roller stops for a short time when measuring a traveling distance by providing a touch roller separately from a driving steering wheel. <P>SOLUTION: This controller 20 calculates the first movement amounts from the number of rotation of a motor 23 for traveling, and calculates the second moving distance from the number of rotation of a touch roller 21. The controller executes a first step to calculate a difference between the first and second movement amounts when the the first or second movement amounts exceed a value L1 and a second step to calculate the current location by using the second movement amounts when the difference is not more than a value L2 however, (L1≥L2), and to calculate the current location by using the first movement amounts when the difference is larger than the value L2. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
